Title: Method of and apparatus for feeding metal sheets and the like to rotary printing or like machines
IPC: B65H9/00
Filed: 1932-12-16
Abstract: 408,744. Feeding metal &c. sheets. MANN & CO. (1932), Ltd., G., Hunslet, and WRIGHT, J. L. R., 22, Parkland Drive, Stonegate Road, both in Leeds. Dec. 16, 1932, No. 35749. [Class 100 (i).] In a method of feeding sheets of metal, cardboard, &c. to a rotary printing or like machine, the sheets are fed without a substantial drop on to a feed-plate or support and up to front lays or stops, and while at rest on the feed-plate are registered and thereafter positively transferred from the registered position to the cylinder grippers. The sheets are positively transferred from the feed-plate to the machine by a sliding gripper action. The metal sheet 1 is fed by rollers 2, 3 on to a feedplate 4, situated slightly below the nip of the rollers, against rising and falling front stops 6, and is held against the latter by one or more movable spring-loaded fingers 7 adapted to project through slots in the plate 4. While the front registration is taking place the sheet is pushed by a side sliding member 8 against a fixed side lay for side registration. The sheet is then gripped against pads 17 by grippers 9 carried by a cross member 10 arranged to slide backwards and forwards between an impression cylinder 11 and an adjacent cylinder 12, which may be a forme cylinder with a printing-surface 14 of larger radius than the rest of the cylinder. The member 10 is mounted on slide bars 20 each pivoted at one end on a shaft 21 and at the other to a connecting rod 19. The sliding movement of the bar 10 is effected by a cam 15 and levers 15<a>, and the timing is such that the bar 10 and grippers 9 move between the cylinders 11, 12 when the smaller radius of the cylinder 12 is presented to the cylinder 11. The grippers 9 are controlled to transfer the sheet to cylinder grippers 16 at the meeting position 16d. During the return movement of the grippers 9 the bars 20 are moved upwardly about the shaft 21, by swinging arms 18 connected to the rods 19 so that the pads 17 upon which the grippers 9 close may descend on the edge of a sheet on the table 4.

Patent GB-893839-A (GB)
Title: New substituted indole-(2)-aldehydes and process for their manufacture
IPC: C07D209/12
Filed: 1958-11-11
Abstract: The invention comprises 1-substituted indole-2-aldehydes, in which the 1-substituent is an unsubstituted alkyl group or an alkyl group substituted by a tertiary amino group, and also salts of the amino substituted compounds.  The preferred 1-substituents are alkyl groups containing 1-5 carbon atoms or alkyl groups substituted by dialkylamino groups, the alkyl substituents of which contain 1-5 carbon atoms.  The tertiary amino groups may, alternatively contain aryl or aralkyl groups.  The new aldehydes are obtained by heating the corresponding 1-substituted indole-2-lithium compound with an N-disubstituted formamide, e.g. N-di-lower alkyl, N-diaryl or N-alkyl-N-aryl formamide, and treating the resulting compound with a hydrolysing agent, e.g. water, a dilute inorganic acid or an aqueous solution of an acid salt.  When the new compounds contain basic groups the salts may be formed if an acid, e.g. hydrohalic acids, sulphuric, nitric, phosphonic, acetic, propionic, oxalic, tartaric, citric and benzoic acids and benzene and alkyl sulphonic acids, is present. The lithium compounds used as starting materials in the examples are obtained by refluxing lithium n-butyl with the corresponding N-substituted indoles in ether solution.  The new aldehydes may be reacted with b -dialkylamino-ethoxy-amines to form the corresponding oximes and these may be quaternated in the usual manner.  For example 1-methyl-indole-(2)-aldehydes may be reacted with b -dimethylamino-ethoxy-amine in alcoholic solution to give the aldoxime <FORM:0893839/IV (b)/1> which on treating with methyl iodide gives O - (b  - trimethyl ammonium - ethyl) - 1 - methyl-indole-(2)-aldoxime iodide.  The new aldehydes can also be converted to p-carbolines, for example, as follows <FORM:0893839/IV (b)/2> <FORM:0893839/IV (b)/3> Examples are given of the preparation of (a) 1-methyl-indole-(2)-aldehyde; (b) 1-methyl-3-dimethylaminomethyl - indole; (c)1 - (b  - diethylaminoethyl) - indole - (2) - aldehyde and 1 - (b -benzyl - methyl - aminoethyl) - indole - (2) - aldehyde.  The 1-methyl-indole-(2)-aldehyde is converted into its thio-semicarbazone by treatment with thio-semicarbazide.

Title: Improvements in or relating to radio receiving systems
IPC: H04B7/12
Filed: 1946-12-11
Abstract: 637,374. Diversity receivers. RADIO COR. PORATION OF AMERICA. Dec. 11, 1946, No. 36642. Convention date, Dec. 11, 1945. [Class 40 (v)] A diversity receiving system for telegraph signals comprises a plurality of pairs of aerials, a receiver with amplifying and frequency reducing means being associated with each aerial, a common signal output circuit for each pair of associated receivers and means for selecting that common signal output circuit having the best output. Fig. 1 shows a system comprising a pair of diversity receivers A and B, each comprising two separate auxiliary receivers, and suitable for the reception of a modulated carrier comprising several channels of frequency shift, tone modulated telegraph signals. Each auxiliary receiver includes a high-frequency amplifier and converter 10, feeding an intermediate frequency stage 16. The outputs from the detector stages D, D<1> of the two auxiliary receivers of receiver A are combined in resistance 20 from which energy is applied to audio frequency amplifier 30. Automatic gain control to both auxiliary receivers is provided by means of resistance R and condenser C. The output from amplifier 30, consisting of the various channel tones, is applied to channel selector filter circuits 1, 2 and 3. In each channel, the frequency shifted tone is then applied to limiter 40, frequency discriminator 50 and detector 60. The output from receiver B is similarly applied to units 40<1>, 501, 60<1>. The outputs from 60 and 601, which are direct currents varying between two values corresponding to marks and spaces, are applied to the grids of gating valves 80, 80<1>. The gating control of these valves is effected by means of a device 90 which supplies differentially varying potentials to the first grids of valves 80 and 80<1> according to the relative value of the outputs from the channel selector units of receivers A and B, so that output from the strongest receiver only is passed to locking circuit 92 to operate printer 94. Since detection takes place prior to the gate switching operation, the distortion due to phase change on switching is substantially eliminated. Further description of several elements of the system is given in Specification 635,263. An alternative arrangement is described (Fig. 2, not shown) in which the gating takes place at intermediate or tone frequency. The arrangement resembles that of Fig. 1, except that the output from limiter 40 is applied to a frequency multiplier 92 and then via limiter 96 to the gating valves 80 and 80<1>. The output from the "open" valve 80 or 80<1> is applied to a limiter, frequency discriminator and detector unit 100 and then to tone keyer 102 and other transcribing devices. If desired, a frequency divider 104 can be included after the gating control circuit. It is shown that the introduction of frequency multiplication before the gate switching operation reduces the distortion caused by phase changes during switching.

Abstract: 1,062,187. Electro-mechanical delay line. WESTERN ELECTRIC CO. Inc. Sept. 19, 1963 [Sept. 26, 1962], No. 36877/63. Heading H3U. An ultrasonic delay line for use at microwave frequencies comprises a magnetic crystal transducer (13) having substantial gyromagnetic properties mounted upon a non-magnetic delay crystal (12), the two materials having such similar crystal structures that at their interface they form a continuous crystal lattice. The transducer may be produced by growing a crystal of suitable magnetic material upon a face of the delay line material, e.g. magnetic yttrium iron garnet upon non-magnetic yttrium aluminuim or gallium garnet, or magnetic magnesium iron oxide upon magnesium aluminate. In the device illustrated, a D.C. field (H) is applied to the transducer and has a strength such that the gyromagnetic material (13) is biased into the neigh bourhood of ferro-magneticresonance, and input energy at microwave frequencies is applied by a coaxial line (15, 17) connected as illustrated to a conductive ring (16) surrounding the end of a rod (12) and the transducer (13). As a result of magneto-striction and gyromagnetic precession about the biasing field H, circularly polarized acoustic waves are excited in the layer (13) and transferred to the delay rod (12) and output transducer (14) &c.

Abstract: 760,467. Phase-equalizing waveguide circuits. WESTERN ELECTRIC CO., Inc. Dec. 21, 1954 [Dec. 31, 1953], No. 36903/54. Class 40 (8). [Also in Group XL (c)] A phase-delay equalizing circuit for a broadband waveguide transmission system comprises an electrically or physically tapered reflecting waveguide which has a delay v. frequency characteristic complementary to the dispersive characteristic of the system. The reflecting waveguide may be physically tapered from a maximum dimension which is greater than cutoff for the lowest frequencies in the band to a minimum dimension which is less than cut-off for the highest frequencies in the band. Each frequency component is thus reflected from a different cut-off point in the tapered guide and the path lengths will increase with frequency. Hence the phase delay introduced by the tapered guide will have a frequency characteristic which compensates for frequency dis. persion in the system. Phase distortion in a long waveguide 22 may be compensated by tapered reflecting waveguides 24, 25 in the arms of a hybrid junction 23 of the Magic-T type. Wave energy from the guide 22 is divided equally between the two tapered arms 24, 25 whence, after reflection, it is coupled into the output arm 26. The apparatus may be used as a pulse-sharpener in a pulse echo system. In a modification (Fig. 3), the Magic-T junction is replaced by a slot coupler 31 which effects an equal division of input power between the delay-equalizing waveguides 32, 33, the reflected waves being combined in an output waveguide 35. The waveguides 32, 33 are carefully matched and are clamped together to avoid difference in dimensions due to temperature changes. Adjustments to the phase-delay characteristic can be made by means of sets of screws 41, 42 which lie respectively perpendicular and parallel to the electric vectors.
